15.45Production debugging

Suppose customer request failed.

Recommended investigation flow:

1. Get correlation ID

2. Find Mule request/error log

3. Identify failing processor/system

4. Determine error category

5. Check retries

6. Check Salesforce state

7. Determine:
   did operation commit?

8. Decide:
   retry / reconcile / fix data / fix config

Don't immediately replay request until you know whether the first write committed.

Module 12 again.
